Virat Kohli returned to form with a classy century as India claimed a thumping win against Australia in their series opener and stand-in skipper Jasprit Bumrah said the veteran batsman's importance to the side cannot be overstated.

India laid down a marker as they completed a sensational 295-run victory over Australia in the first Test in Perth. The hosts were bowled out for 238 shortly after tea on day four, as India wrapped up a big win and made a perfect start to the five-match series.
